TextureSwiftSupport - Gains up your productivity

This is a library to gain Texture(AsyncDisplayKit) more power in Swift.

• Readable Layout DSL
• Composable components

And you might need to use TextureBridging to integrate with AutoLayout world in your applications.

Requirements

Swiift 5.3+

The cases of usage in Production

Layout DSL

Using resultBuilders, ASLayoutSpec can be more simply and readable it's like SwiftUI's decralations.

🕺🏻 You want to use this in AutoLayout?

Before

override func layoutSpecThatFits(_ constrainedSize: ASSizeRange) -> ASLayoutSpec {

  ASStackLayoutSpec(
    direction: .vertical,
    spacing: 0,
    justifyContent: .start,
    alignItems: .start,
    children: [
      self.textNode1,
      self.textNode2,
      self.textNode3,
    ]
  )
  
}

After

override func layoutSpecThatFits(_ constrainedSize: ASSizeRange) -> ASLayoutSpec {

  LayoutSpec {
    VStackLayout {
      self.textNode1
      self.textNode2
      self.textNode3
    }
  }
  
}

Wrapping with LayoutSpec enables us to write DSL inside this block.

More complicated example

LayoutSpec {
  if flag {
    VStackLayout {
      HStackLayout(justifyContent: .center) {
        iconNode
          .padding(.top, 24)
          .padding(.bottom, 16)
      }
      .background(gradientNode)
    }
  } else {
    gradientNode
  }
}

⚠️ Please take care of the differences between this DSL and SwiftUI.
This DSL just describes the node's layout. You should avoid to create a new node inside layout.
Since layoutSpecThatFits would be called multiple times.

Layouts

• Basic Layouts

  • VStackLayout
  • HStackLayout
  • ZStackLayout
  • WrapperLayout
  • AbsoluteLayout
  • CenterLayout
  • RelativeLayout
  • InsetLayout
  • OverlayLayout
  • BackgroundLayout
  • AspectRatioLayout
  • SpacerLayout

• Advanced Layouts

  • VGridLayout
  • AnyLayout
  • Switch

Modifiers

• WIP

Composable components

TextureSwiftSupport provides us a lot of components that help to create a new component with compositioning from small components.

Technically, composing increases a number of view or layer in run-time. It might reduce the performance a bit.
But most of the cases, that won't be matters.

• MaskingNode
• BackgroundNode
• OverlayNode
• PaddingNode
• WrapperCellNode
• WrapperNode
• ShapeLayerNode
• ShapeRenderingNode
• InteractiveNode
• AnyDisplayNode
• GradientNode
